Charging handle install problem

I hope this ends up being easy. My charging handle is not installing in my upper. I have seen the two tabs on either side that drop down in the upper so that it will hit the groove. I do that, but it will not slide forward.

Another thought, if you can get the charging handle into the track and then it slides forward some but not all the way, it may be hitting the gas tube. Make sure the gas tube is lined up properly.

Try a diff charging handle or two. I did get in a brand new PSA upper last summer that was extremly tight. Seems like the channel had too much parkerizing or something in there. I was able to apply lots of oil and manually strong arm it enough to get it working.

During the first range trip it was a !title sticky if you didn't let the bolt slam home with the full strength of the spring behind it. But after that first trip and a super thorough cleaning after it has run perfectly.

I have ONE billet upper that simply isn't machined properly requiring the CH be ground to fit the "track".
BTW I don't think it's possible to install the CH upside down.

A couple of my assemblies, getting the CH in at first was a little tight. Gas tube is a possibility as well, but you wouldn’t be able to get the BCG in either.

Trying to post a picture, it would help if they allowed pictures larger than a postage stamp. It is a PSA charging handle with a cerakoted aero precision upper. It fits in the slots in the upper but doesn't slide in after that. Not hitting the gas tube, not even getting that far.

Id try another charging handle. That one may be out of spec.

Doesn’t go in very far at all. Gas tube not in play anyway.
Probably will have to try another charging handle.
I’ve had a couple that I thought wasn’t going to fit, but they ended up working.

My money is on the PSA part being out of spec.

Aero makes good stuff.

Call PSA and they will probably swap that CH for another one. While their parts can be junk, they generally do have good customer service.

Maybe it just the photo, but the charging handle looks wide on the lower side of the channel (at the cut out) in your second photo.

"with a cerakoted aero precision upper."

AHA!!! Found your problem!!! Slobbery application of cerakote can/will cause parts interference.

Yea, I think you have a messed up charging handle. I can see a bow in that second picture too that looks to be jamming it in the channel.

Swap out another one and try it.

either the upper is out of spec or the charging handle is. I would call PSA and talk to them about it.

I doubt that you would have a problem like that from Aero Precision.

Everyone makes mistakes and sometimes bad eggs get through good QC, but Aero is downright OCD about that stuff.

It was the charging handle. Purchased a new one and it literally fell into place. Thanks for the help. Build is finished.

darn right! I’ve purchased parts that they call “blemished” and could never find a flaw aside from a surface scratch that was in a place that wasn’t visible after assembly. Probably could’ve been buffed out.

Well, I'm not a member of the Aero lovefest patrol--I've had all kinds of fitment problems with their AR10 platform stuff.

In the photo of your completed rifle, it looks like your flip up sights have been installed backwards. . .

Unless that's how you like them.

What kinds of problems? I built up on their DPMS pattern and it was good to go. I had to buy their LPK to ensure no headaches and I was glad I did.

The 2 lowers I've bought from them both have erratic line-up with other DPMS style uppers--as well other's LPK's don't always work well with their lowers (which isn't too surprising, but the fit is generally the worst of any xx308 lower I've ever used, at least in terms of fitting other's uppers besides their's).
